g is a specification.

:To all whom it may concem a Be it known that I, THOMAS "UNITED STATESPATENT OFFICER THOMAS J. JONES, or TRUMBULL counr'r, 011 0;;

citizen ofthe United States, residing in the county of Trumbull andState of Ohlo, have invented certain new and useful Improvements inNut-Locks, of which the following My invention relates combination withbolts of, means for preventing the loosening of the nuts; this in-,vention is directed tothat class of bolts having lock nuts thereon onwhich the threaded end is provided with right and lefthand screwthreads, and has for-its object, means for preventing the accidentalloosening of the nuts. I

I A further object is to provide means 1nteracting between the nut' onthe right hand. thread and the nut on the left hand thread forpreventing the independent turning of these nuts.

Further ob ects and purposes of my invention will up 3.1 from aninspection of,

the drawings, t e specifications describing the same, and the claimsappended thereto, in which are set forth the eatures of construction,combination of elements, and arrangement of parts, properly comprisedwithin the scope of the same.

In the drawing in which is illustrated one of the possible embodimentsof .my invention; F1 re 1 shows a right and left hand threade bolt withnuts thereon and my lockin washer inteposed between the nuts, the ho tand nuts being shown in a side view and in connection with a rail andfish plates which are shown in vertical cross section. Fig. 2 is a frontview looking at the nuts and washer as a plied to the bolt in Fig. 1.Fig. 3 shows t e conventional form of a right and left hand threadedbolt such as used in carrying out my invention. Fig. 4 is my washershowi its edges turned up at the points requir to retain the nuts whenpositioned as shown in Figs. 1 and 2. Fig. 5 is a vertical crosssectional view of my washer as shown in Fig. 4. Fi 6 shows the ordinaryform of the washer fore the ed es are bent to lock the nuts. I

eferring now to the several figures as above described in which likereference characters designate like parts, (1) is a conventionalformof-Tgrail'aiid 2) J. Jones,

a, bolts and the Specification ofLettersPatent. a Paten ;..1y 1 1 platesused at the joints of suchr'zii (filrepresents the bolt and.he ad,.;thand thread at (4), anda reduo (4) is a threaded nut adapted to sit n Ithe enlarged threadedsection and 5, abut.- with threads corresponding.to (5') and ada ted to screw on the reduced portion.

y locking means is an ordinary ,metallic washer (6), the. diameter ofwhich, however, should be equal or greater than the lengths ofa diagonalline d13.WIl between the oppositecorners of the nuts. This disk orwasher has a circular aperture in it sufficiently large to pass freelyover the larger threaded section 4. t The washer is made... from sometough metal and should assess no resiliency, a Zinc compound pre erablyentering into its composition. 3

Owing to the 'difl'erence in diameter of the threaded sections, therelation of the sides of the nuts to each other will vary according tothe ultimate position of the inner nut, and so inasmuch as it isnecessary to lock nuts whether their sides be flush or not, 111invention is so adapted. as to be capab e of locking nuts whenever theyare ti ht a ainst each other and irrespective of time re ative 35position of the side faces.

lVhen, in tightening the nuts, the inner and outer nuts bear therelation toward'each other as shown in Fi s. 1 and 2, the edge of thewasher is hit with any hammer or other so too] and bent down upon theinner nut, as shown at (7) a blow outward on the opposite side of thewasher will turn the edge up to embrace a side of the. outer nut asshown at (8). Thisxsim le operation with my invention rigidly s the nutsin re- V spect to each other and prevents their accidental unscrewing.Moreover, the very simplicity of the device is such that makes itunnecessary 'to provide specially designed .100 nuts or special .toolsfor locking thesaurus;- and as an inspection of the drawings willdisclose, my device is equally operative and valuable in any positionthe nuts may bear relative to each. other.

I am Well aware of the prior art in which is disclosed means inter osedbetween the nuts on a right and left and threaded belt for locking thenuts, butI claim asnew, the means operative without a special structure110 of the nuts to lock the nuts in whatever position they may be inrespect to each other.

Having thus described my invention,what I claim as new and desire tosecure by Letters Patent, is;

1. Incombination, a bolt having at one end a: right hand threadedsection and a left hand threaded section, nuts correspondand a metalliclocking member located on s'aitl', bolt between the nuts and adapted toprevent the movement of the nuts relative to each other, sald memberbeing operative in any position of the nuts in respect to'each other andcomprising a circular washer having a single aperture therein,substantially as shown and described.

3. The combination of a right and left hand threaded bolt, nuts appliedthereto, a plain washer ofa relatively large diameter interposed betweenthe nuts, said washer being bent in one direction to embrace a side ofone of the nuts, and m the opposite direction, to embrace a side of theother nut,

whereby the nuts are locked relatively to each other in whateverposition they occupy in respect to each other, substantially as shownand described.

4. In combination, a bolt having a head at one end and a ri ht handthreaded section at the other en a reduced left hand threaded sectionintegral with said bolt and located exteriorly of the right handsection, a threaded nut screwed u )011 the right hand threaded section,a second nut screwed upon the exterior section, a plain metallicnonresilient washer of relatively large diameter interposed between thetwo nuts, and flanges on said washer bent in opposite directions andembracing one or more sides of each nut. whereb the nuts are locked inany position relative to each other, substantially as shown anddescribed.

In testimony whereof Iaflix my signature in presence of two witnesses.
